Review Comment:
With this line we get the exception `java.lang.IndexOutOfBoundsException:
Index 3 out of bounds for length 1` (which is the original one described in the
ticket); without it we get a different (related) one `java.lang.AssertionError
at
org.apache.hadoop.hive.ql.parse.type.TypeCheckProcFactory$DefaultExprProcessor.getXpathOrFuncExprNodeDesc(TypeCheckProcFactory.java:881)`
, which is the same one as in the other new q file.
Both go away with the patch.
